Question

Transcribed Image Text:8.3. Now imagine if you removed one hydrogen from methane and added a second carbon and its associated
hydrogens. This would create ethane. Draw your completed ethane molecule below (ball and stick model).
8.4. What is the chemical formula for ethane?
8.5. Observe your ethane molecule. Are there any polar covalent bonds present? .
8.6. Based on your answer would your predict that ethane would or would not dissolve easily in water?
8.7. Now imagine taking off one hydrogen from ethane and adding a hydroxyl group in its place. Draw your
completed ethanol molecule below,
8.8. Ethanol is an alcohol found in drinks such as beer and wine. Examine this molecule. Are there any polar covalent
bonds present?
8.9. Based on your answer, would you predict that ethanol would or would not dissolve easily in water?
8.10. Carbon can form bonds with itself and other atoms. Long chains of carbons are common in nature; starch -a
very long chain of glucose molecules- is a good example. Is there any limit (in theory) to the number of bonds
carbon can form with itself?
9. Your basic organic molecule. Organic molecule in the human body fall into four categories.
9.1. What are the four types of organic molecules?
Carbohy drotes
Lipids
• prodeins
Nuclec Acids
